Data Sheet

EM-PME375-T200

Electric machine, permanent magnet external

FEATURES

• Synchronous Reluctance assisted Permanent

Magnet (SRPM) technology

• Extremely compact and robust structure

• Highest efficiency throughout the operation range

on the market (~96 %)

• Liquid cooled with plain water or water/glycol

mixture

• Low coolant flow required

• Allowed coolant temperature up to +65°C

• Up to IP65 enclosure class to maximize reliability

• Multiple mounting possibilities

GENERATOR SPECIFIC FEATURES

• Standard SAE flange mounting to match the diesel

engine connection

• Wide

• Can be also used as starter motor for the ICE

selection of speed ratings allowing the

generator to be selected to customer specific

applications with various voltage requirements

MOTOR SPECIFIC FEATURES

• Extended speed and torque capabilities compared

to standard PM motors from Danfoss reluctance

assisted permanent magnet motor technology

• Motor structure is designed to be able to produce

high starting torque: EM-PME motor can produce

instantly full torque to a non-rotating shaft

• Optimized speed range to meet the most common

gear ratios used in heavy mobile machinery

GENERAL

The machine is developed especially for demanding
applications. The design of these machines makes them
smaller, lighter and more efficient than conventional
products on the market.

The machine is designed to be shorter than normal motors
for applications where axial length is crucial parameter. The
machine is designed to be connected directly to the ICE
flywheel housing with part of the motor being inside the
flywheel housing further shortening the length of the motor.

TYPICAL APPLICATIONS

• Generator for diesel-electric/serial hybrid

applications

• Traction/propulsion motor

• Generator/Motor for parallel hybrid applications
